We've all got emojis down, and text speak, and every other linguistic shortcut.

But a new list of punctuation marks could help to create the pinnacle of perfect language.

As so much of the communication between smartphone and online users is without tone, these can help to show when you're being sarcastic, sincere, or just out-and-out mocking.

The hilarious suggestions come from the College Humour site and were shared on Reddit.

User Antivax-Jugalette called the post " Some proposed new punctuation ", and commenters loved them.

Jungle Love Child joked: "My first attempt at dating would have gone smoother if I had the third one," while Will McAvoy added: "This could actually be a legitimate need in the near future. We communicate so much through text nowadays that eventually society will have to agree on a sarcastic identifier."
